void ExpandingDelegate::adjustRect

(

QRect &

rect

)

const [protected]

Definition at line 142 of file expandingdelegate.cpp.

void ExpandingDelegate::adjustStyle	(	const QModelIndex &	index,
		QStyleOptionViewItem &	option
	)			const [protected, virtual]

Reimplemented in KateCompletionDelegate.

Definition at line 138 of file expandingdelegate.cpp.

QSize ExpandingDelegate::basicSizeHint

(

const QModelIndex &

index

)

const

Definition at line 119 of file expandingdelegate.cpp.

QList< QTextLayout::FormatRange > ExpandingDelegate::createHighlighting	(	const QModelIndex &	index,
		QStyleOptionViewItem &	option
	)			const [protected, virtual]

Reimplemented in KateCompletionDelegate.

Definition at line 113 of file expandingdelegate.cpp.

void ExpandingDelegate::drawBackground	(	QPainter *	painter,
		const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)			const [protected, virtual]

Definition at line 280 of file expandingdelegate.cpp.

void ExpandingDelegate::drawDecoration	(	QPainter *	painter,
		const QStyleOptionViewItem &	option,
		const QRect &	rect,
		const QPixmap &	pixmap
	)			const [protected, virtual]

Definition at line 275 of file expandingdelegate.cpp.

void ExpandingDelegate::drawDisplay	(	QPainter *	painter,
		const QStyleOptionViewItem &	option,
		const QRect &	rect,
		const QString &	text
	)			const [protected, virtual]

For some reason the text-formats seem to be invalid in some way, sometimes

Todo:

Fix this properly, it sucks not copying everything over

Definition at line 154 of file expandingdelegate.cpp.

bool ExpandingDelegate::editorEvent	(	QEvent *	event,
		QAbstractItemModel *	model,
		const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)			[protected, virtual]

Definition at line 295 of file expandingdelegate.cpp.

void ExpandingDelegate::heightChanged

(

)

const [protected, virtual]

Reimplemented in KateCompletionDelegate.

Definition at line 292 of file expandingdelegate.cpp.

QList< QTextLayout::FormatRange > ExpandingDelegate::highlightingFromVariantList

(

const QList< QVariant > &

customHighlights

)

const [protected]

Creates a list of FormatRanges as should be returned by createHighlighting from a list of QVariants as described in the kde header ktexteditor/codecompletionmodel.h.

Definition at line 315 of file expandingdelegate.cpp.

void ExpandingDelegate::initStyleOption	(	QStyleOptionViewItem *	option,
		const QModelIndex &	index
	)			const [protected]

ExpandingWidgetModel * ExpandingDelegate::model

void ExpandingDelegate::paint	(	QPainter *	painter,
		const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)			const [virtual]

This is a bug workaround for the Qt raster paint engine: It paints over widgets embedded into the viewport when updating due to mouse events

Todo:

report to Qt Software
